Quick Start

Step uses sbt, a fantastic tool for building Scala programs. For instructions, see the sbt site

Run sbt

In the directory you downloaded step to, run sbt.
sbt will download core dependencies, and Scala itself if it needs to.

Download dependencies

At the sbt prompt, type update. This will download required dependencies.

Try it out

At the sbt prompt, type jetty-run. This will run step with the example servlet on port 8080.

Navigate to http://localhost:8080

You should see "Hello world." You can poke around the example code in src/main/scala/StepExample.scala
to see what's going on.

Supported Methods

before

Run some block before a request is returned.

get(path)

Respond to a GET request.

Specify the route to match, with parameters to store prefixed with : like Sinatra.
"/match/this/path/and/save/:this" would match that GET request, and provide you with a
params(":this") in your block.

post(path)

Respond to a POST request.

Posted variables are available in the params hash.

delete(path)

Respond to a DELETE request.

put(path)

Respond to a PUT request.

Sessions

Session support has recently been added. To see how to use sessions in your Step apps, check out the test servlet, at src/test/scala/StepTest.scala

Testing

A test suite can be found in src/test/scala. Inside StepTest.scala is a small testing servlet along with some assertions. If you've made changes to Step itself and you'd like to make sure that this testing servlet still works, you can type test at the sbt prompt.

Miscellaneous

While Step can be run standalone for testing and meddling, you can also package it up in a .jar for use in other projects. At the sbt prompt, type package. Step's only dependency is a recent version of the servlet API. For more information, see the sbt site

Props

I'd like to thank Gabriele Renzi for the inspirational blog post and continual help, and Mark Harrah for help on the sbt mailing list and for creating sbt. Ant+Ivy by itself was a total bitch.

I'd also like to thank Yusuke Kuoka mumoshu for adding sessions support.
